Abstract
The invention relates to a device for externally immobilizing broken bones, particularly bones of the extremities. According to the invention, the device has a multi-articulartion rod that can be placed on the outside of the body while extending along a broken bone. This rod comprises elements (1), which can move in relation to one another and can be fixed in appointed directions. One of the elements (1) has a bone pin (7), which can be held therein in a manner that permits it to turn and which is provided for being anchored inside the bone. In addition, the tip of at least one of the bone pins (7) is provided in the form of a screw having a self-tapping thread (8).
Description
Technical field
The present invention relates to be used for fixing outside the device of knochenbruch.
Background technology
This device is disclosed by DE19746687A1.The nail of this known devices has slick tip, and here, the nail that is rotatably supported in these links especially is pressed in the bone with hands under the situation of using small-sized electric drill with exerting pressure.Bulged-in nail is fixed on the device link under the nail by tightening to locking nut on the link.
The weak point of known devices is, nail is pressed into the quite high equipment cost of requirement, and because the nail tip is slick, so for anchoring reliably just must be pressed into nail in the bone deep, in the method, provide by electric drill and also be that essential high rotating speed causes bone unnecessarily damage strongly around nail.
Summary of the invention
Thereby task of the present invention is to improve the device of above-mentioned fixation of bone fragments outside, to guarantee to realize the secure fixation of nail under the as far as possible little situation of bone load.
In order to finish above-mentioned task, the invention provides a kind of device of fixation of bone fragments outside, this device has many toggles of arranging at health outer knochenbruch, these many toggles have the link energy relative accommodation and that can be fixed on its direction on the setting direction, the part of these links has a nail that remains on rotationally wherein, be used to be anchored in the bone, the tip of one of them nail is configured to the form of the screw of tapping screw thread, it is characterized in that, the described nail that its tip is screw-type can be directed in affiliated link by self-locking thread on its bar with turning, and the pitch of the screw thread on the nail tip and the pitch of self-locking thread are about equally.
Utilize such nail embodiment, just can be or by suitable instrument such as wrench or screwdriver nail is screwed in the bone where necessary with hands, and this moment as the cork bottle opener in cork, it is fixed in the bone.Compare and the much smaller degree of depth that pierces to be enough to make the nail secure fixation in bone with known nail.In addition, can realize that the nail that is screwed into can remain on its turned position under the situation of other measure not having, thereby avoid in bone, withdrawing automatically.
According to the present invention, for being led in this link, moves by the nail bar, be provided with one can rotate but can't along its axis direction remain on movably in this link and can manual knurled nut, most advanced and sophisticatedly become the self-locking thread of the nail of screw-type to mesh with the knurled nut.Thus one, the device link that can make the supporting nail nail be screwed into the back relatively bone carry out altitude mixture control.Treat that fixed bone is brothers' bones here.
Description of drawings
A preferred embodiment of the present invention below is described with reference to the accompanying drawings.Accompanying drawing is depicted as:
Fig. 1 represents the externally apparatus of the present invention of fixation of bone fragments that are used for that are contained on the finger,
Fig. 2 (a)-2 (d) is with side view, rearview, represent a device link from vertical view and three-dimensional view, and it is equipped with the nail that can be screwed in the bone.
The specific embodiment
As shown in Figure 1, fixture has a series of link 1, and this can see better from Fig. 2 that their mutual universal hingings together.Each link at one end has a ball 2 and at the other end ball-and-socket 3 is arranged, and here, the ball 2 of a link is respectively charged into 3 li of the ball-and-sockets of next link.The relative position of the universal hinging link of getting up fixes by the bail 6 that surrounds ball-and-socket in this way, by this bail, makes the ball-and-socket 3 because of seam 11 energy strains are arranged be pressed towards the ball 2 that is contained in wherein.
The nail of common form is positioned on the end of fixture, and these nails for example can be clamped ailhead 4 and are rotatably fixed on its link that is positioned at a locking nut 5 is anti-after hammering into bone with an electric drill.
One embody nail 7 of the present invention at one on the link between the two ends.This nail is made of a screw, and it has a tip, and tapping screw thread 8 is arranged on the tip, and this is similar to self-tapping screw or cork bottle opener.When being screwed into bone, nail is just followed closely in bone.So, when piercing the degree of depth less than in traditional nail the time, as it at the two ends of fixture shown, can obtain stability.
If after being screwed in the bone, knurled nut 9 is fixed and turned to nail 7 to nail 7, the link that nail 7 then is housed just relatively bone carry out height adjustment.Screw thread is self-locking in and also is used to make the position of current adjustment can not change automatically here.
Shown in form of implementation in, has just constituted and be positioned at intermediary nail, and the nail that is positioned at the end is a traditional form according to the present invention ground.But can certainly according to Fig. 1 in the same mode of intermediary nail that is positioned at constitute more than one nail and all nails.
Claims (3)
1. the device of fixation of bone fragments outside, this device has many toggles of arranging at health outer knochenbruch, these many toggles have link (1) the energy relative accommodation and that can be fixed on its direction on the setting direction, the part of these links (1) has a nail (7) that remains on rotationally wherein, be used to be anchored in the bone, the tip of one of them nail (7) is configured to the form of the screw of tapping screw thread (8), it is characterized in that, the described nail (7) that the tip is screw-type can be directed in affiliated link (1) by self-locking thread (10) on its bar with turning, and wherein the pitch of the pitch of the screw thread on this nail tip and this self-locking thread about equally.
2. by the described device of claim 1, it is characterized in that, for this nail bar is moved in this link (1) lining guiding, be provided with one can rotate but can't along its axis direction remain on movably in this link and can manual knurled nut (9), the most advanced and sophisticated self-locking thread (10) and this knurled nut's engagement that becomes the described nail (7) of screw-type.
3. by claim 1 or 2 described devices, it is characterized in that, describedly treat that fixed bone is brothers' bones.
